386 Mr. G. C. Champion on the Tenebrionidx 
outwardly directed humeri, each elytron with three longitudinal 
equidistant coste extending to considerably beyond the middle, the 
inner one stout, smooth, and shining, and strongly raised, the other 
two faint and slightly crenulate, the external one curving inwards 
at the base, the space between the first costa and the suture (which 
is not raised and slightly shining) quite flat, and between it and 
the lateral margin obliquely declivous, the interspaces shagreened 
and very minutely granulate, and with rows of subobsolete punc- 
tures, a row of coarser impressions midway between the outer 
costa and the margin, the margins moderately horizontally ex- 
planate, the exterior edge not thickened ; the legs and under 
surface fusco-ferruginous ; the prosternum granulate, longitudin- 
ally wrinkled at the sides, the prosternal process rugosely punctured, 
the latter subhorizontally produced, and received by the deeply 
excavate V-shaped mesosternum; the rest of the under surface 
thickly punctured and wrinkled, the pleura smoother ; anterior 
tibiz with a short fine tooth at the outer apical angle. Length 164, 
breadth 10 mm. 
Hab. N.W. Australia—Roebuck Bay. 
One specimen. Very near S. confirmatus, Pasc., from 
W. Australia, but much larger, broader, and more robust, 
the legs much stouter; the innermost costa on the 
elytra stouter, more raised, and shining, the other costz 
faint (not being any more prominent than they are in 
S. confirmatus); the prothorax not wider than the elytra 
at the base. Another closely allied, perhaps undescribed, 
species, from Nicol Bay, is contained in Mr. F. Bates’s 
collection. S. bicarinatus is apparently not described in 
MacLeay’s monograph of the genus. 
Saragus intricatus, n. sp. 
Oblong-oval, very convex, black, subopaque. Head sparsely 
and very finely punctate, the interocular space more coarsely and 
more closely punctured ; prothorax at the base more than twice as 
broad as long, broadly and very deeply emarginate in front, the 
sides rapidly and arcuately converging from the base, the base 
feebly emarginate in the middle, broadly rounded to the outer 
limit of the disc, and then very obliquely truncate to the sharp 
posteriorly-produced hind angles, the disc transversely convex, 
shallowly longitudinally grooved in the middle behind, and thickly, 
very finely punctate, the margins strongly horizontally explanate, 
and finely shagreened, the outer edge not reflexed, the anterior 
angles rounded ; scutellum smooth; elytra slightly wider than,
